Diagnosis and treatment of paranasal sinus fungus ball of odontogenic origin: case report.

In recent years the incidence of fungal sinusitis has increased considerably, due both to increased survival of patients at risk and to improved diagnostic equipment. The pathogen responsible in most cases is the Aspergillus in its forms Fumigatus, Flavus and Niger. The diagnosis is often delayed because the symptoms, characterized by headache, cough, and facial algia, are generally similar to that of chronic bacterial rhinosinusitis.

Clinical evaluation of percutaneous vertebroplasty in a patient with paraplegia and immobilization syndrome: a case report.

We will discuss a potential role of percutaneous vertebroplasty (PVP) in the management of a patient with immobilization syndrome due to paraplegia and vertebral osteoporotic fractures. While PVP is commonly used for the treatment of osteoporotic thoracolumbar vertebral compression fractures, its role in vertebral stabilization in patient with immobilization syndrome has not been reported in the literature. A 73-year-old woman affected by immobilization syndrome due to paraplegia and vertebral osteoporotic fractures was treated with PVP of vertebrae D12, L1, and L4.

Early magnetic resonance detection of natalizumab-related progressive multifocal leukoencephalopathy in a patient with multiple sclerosis.

Diagnosis of progressive multifocal leukoencephalopathy is usually based on the clinical presentation, on the demonstration of the brain lesions at the magnetic resonance imaging examination, and on the detection of the JC virus DNA in the cerebrospinal fluid with high sensitive polymerase chain reaction. The role of magnetic resonance imaging specifically in natalizumab-associated progressive multifocal leukoencephalopathy is strengthening, and it is gaining importance not only as an irreplaceable diagnostic tool but also as a surveillance and risk stratifying tool in treated patients. While other imaging techniques such as computed tomography lack sensitivity and specificity, magnetic resonance performed with morphological and functional sequences offers clinicians the possibility to early identify the stage of the disease and the emergence of an immune reconstitution inflammatory syndrome after natalizumab blood removal plasmapheresis.

Cone Beam CT use in the pre-prosthetic evaluation of endodontically treated of the rear maxilla.

With our study we wanted to compare the diagnostic accuracy of conventional radiography (orthopanoramic and intraoral radiography) and Cone Beam CT (CBCT) for the diagnosis of periapical lesions on the posterior elements of the upper maxilla endodontically treated.The images were analyzed by a radiologist and an endodontist whose interpretation of radiological examinations is unique. Were examined 34 molars (23 first molars and 13 second molars) with a total of 102 roots.

Cloning and characterization of a lung-specific cDNA corresponding to the gamma chain of hepatic fibrinogen.

The gene (gamma FBG) encoding the fibrinogen gamma chain (gamma FBG) has been shown to exhibit both tissue-specific and ubiquitous expression. To confirm the identity of the gamma FBG transcripts expressed in extrahepatic tissue, lung tissue was chosen as a model of extrahepatic gamma FBG gene expression. A ferret lung cDNA clone bank was constructed in lambda gt11 and several positive plaques were isolated using cross-species hybridization with the rat gamma FBG cDNA.
